lM P ROVEMENTVIN DOOR-BELLS.

Specification forming part of Letters Patent No. 194,023, dated August7, 1877; application filed 7 July 25, 1877.

To all whom it may concern Be it known that I, WILLIAM WINKEL, of

Pluckemin, in the countyof Somerset and being had to the accompanyingdrawings and to the letters of reference marked thereon.

The object I have in View is the production of a bell-striking mechanismto be used in connection with a lever bell-pull, which will be simpleand cheap in construction, durable in use, and can be operated easilyand with great certainty.

- My invention therein consists, first, in a toggle-joint connecteddirectly to the hammer and moved through a portion of the stroke by areciprocating bar operated from the bell-pull, to withdraw such hammer,the said joint being thrown the rest of the distance and the hammer madeto strike the gong by a spring operating independent of the bell-pull;second, in the peculiar means for connecting the bell-pull with thistoggle-joint; and, further,

in the various combinations of the operative parts, as fully hereinafterexplained.

In the drawings, Figure 1 represents a side elevation of the bell andits operating mechanism, mounted in position for use; Fig. 2, a verticalsection of the same on the line of the bell-pull, with the gong removed,and Fig. 3 a view from the rear with the gong removed.

Like letters denote corresponding parts.

A represents a circular cast-metal plate, adapted to be mounted andsecured by woodscrews upon the inner side of a door frame or post, B,and having cast therewith a large central stud, a, for carrying theordinary gong A. On the plate A, on one side of this stud a, is cast asmaller stud, a, upon which is pivoted the hammer O. This hammer is ofthe form shown in Fig. 3, having a short arm, I),

I projecting upwardly from the pivot, and a horizontal lug, 1),extending inwardly from the upper end of the said arm.

A spring, 0, is wrapped around the stud a, inside of the hammer-arm, andbears at its ends against the lug b, and against a small stud, 0, caston the plate A. This spring," by

forcing the arm b inwardly, throws the hammer outwardly in contact withthe g0ng,which outward motion isilimited by another small stud, a.

D is a vertical shifting-bar, sliding in.holes formed in the tops of twowings, (1 (2 which are situated on the opposite side of the centralstudfrom the hammer. This bar is connected at its upper end to aconnecting-link, d which is in turn pivoted to the inner ends of twohorizontal links, 6 6 The link 0 is pivoted at its outer end to the armb, while the link 0 is set on a stud, 6 thus forming a toggle-joint,which operates upon the short arm of the hammer.

E is a short lever, which projects through a slot in the plate A, justbehind the shifting,

bar D, and, when the bell is in position, enters a slot in the frame B.This lever is pivoted in lugs on the back of the plate A, and has twojaws, f f on its outer end, which strike, when moved against a lug, f onthe inner face of the shifting-bar. These jaws are situated such adistance apart as to allow theshifting-bar a limited vertical movementindependent of such jaws. To the lower jaw f is secured a stud, g,projecting from the side of the lever bell-pull with the gong-strikin gmechanism, and its length maybe varied,'as found necessary, to adapt thebell to frames or posts of different thicknesses, or two or more smallerlinks can be used in its place, if found desirable.

The gong and striking mechanism are all carried on the plate A, and thisplate and the bell-pull and its plate are mounted directly opposite eachother, on opposite sides of a door frame or post, the bell-pull and thestriking mechanism being connected in the manner just described.

lever E, stretching the spring h. This movement brings the jaw f intocontact with the lugf 'on the shifting-bar, and the shifting bar beingforced down the toggle joint 0 e is straightened out, and the short armof the hammer pushed outwardly against the pressure of the spring 0,thus drawing the hammer itself away from the, gong. Assoon as thecentral pivot of the toggle-joint passes below the line of its outerpivots thespring 0 bends the joint downwardly and shoots the shittingbarto its lowest position, throwing the hammer with a quick stroke againstthe gong. The spiral spring it will then draw the bellpull and the jawsof the lever E upwardly, the lower jaw f engaging the lug f andstraightening out the toggle-joint, the hammer being at the same timedrawn away from the gong. The toggle-joint passing the straight line thespring 0 will throw it into its highest position, and the hammer willagain strike the gon I A constant resistance is exerted on thebellpulling lever by means of the spring h', so that the'bell-pull isnot affected when the hammer is thrown, while the springcis strongenough to overcome the toggle-joint and throw the hammer withconsiderable force against the gong, thus insuring absolute certainty inthe operation of the mechanism, the gong being struck twice every timethe bell-pull is moved.

The means employed are simple in construction, very durable in use, andcan be operated conveniently and effectively.

Having thus fully described myinvention, and explained some of itsadvantages, what I claim as new therein, and desire to'secure by LettersPatent, is-

1. The combination, in a door-bell, of atoggle-joint having one armjoined directly to the hammer-arm, and the other pivoted upon astationary stud, a reciprocating bar moved by the bell-pull andconnected to the central pivot of the saidtoggle-joint, and a spring.for throwing said toggle-joint outwardly after it has passed a straightline, substantially as described.

2. The combination, with the toggle-joint e e, of the shifting-bar D,having lug f and the lever E, moved by the bell-pull and provided withthe jaws f f substantially as described and shown.

3. The combination, with the shifting-bar D, having lugf and thetoggle-joint 6 6 of the lever E, provided with jawsff the link 70, andthe bell-pull F, substantially as described and shown.

4. The combination, with the toggle-joint e 6 of the hammer G and spring0, substantially as described and shown.

5. The combination, with the lever E, moved by the bell-pull, of theshifting-barD, spring h, toggle-joint e 6 hammer G, and spring 0,substantially as described and shown.

6. The bell-striking mechanism described, wherein are combined the leverbell-pull F, link It, lever E, spring h, shifting-bar D, toggle-joint 0e hammer G, and sp'ringc, all constructed and arranged to operatesubstantially as described and shown.

This specification signed and witnessed this 18th day of July, 1877.
